'2 Claims.

My invention relates to an improvement in side files and jointers forspring and swage tooth saws. In. saws of the spring tooth type, theteeth of the saw are set by pressing or bending one tooth to one sideand the next tooth to the opposite side of the saw and so on the lengthor circumference of the saw. In so setting the saw teeth one tooth maybend easier than another and resulting in an irregular set, then, as thesaw cuts, tooth marks are left on the face of the wood that has been cutand the cut surface of the wood is left rough and irregular. Thisroughness can be overcome if the points of all the saw teeth in eachdirection are set evenly so that all the tooth points are in exactalignment. In view of this, it is the object of my invention to providea device which will cut the set teeth of a saw to exact alignment. A sawthat has been filed, set, and the teeth aligned by my improved tool willmake the saw run easier, smoother, and leave a surface on the wood thatis entirely free of roughness and saw marks.

A further object is to provide a device of the kind mentioned that isapplicable for use on all types of wood saws including the swage toothtype of saw.

Fig. 17 is a front end view of the tool and saw shown in Fig. 16.

Fig. 18 is a side view of the tool and saw shown Fig. 16, the saw beingshown in section. In the drawings the device is shown as having a bodyelement 49 the central portion of which is provided with arcuate lateralextensions 20 and 2| that are integrally formed thereon and the bottomfaces of which are flush with the bottom of the body element 19. Theupper side of the body element [9 is provided with a pair of upwardlyextending ear-like elements 22 and 23, that are parallelly positionedand spaced apart, and their outside faces are flush with the oppositeside faces of the body element I 9, and the ear-like elements 22 and 23are integrally formed on the body element I9.

A curved insert 24 is embedded in the body element l9 and arcuate sideextensions 2!! and 2|, and one edge of the curved insert 2 pro- J'ectsfrom and beyond the bottom face of the body element is and arcuateextensions 28 and 2|. The curved insert 24 is preferably made of steelor hard fiber and acts as a gauge bearing as will later be explained.

The front end of the bottom side of the body element I9 is provided witha transversely positioned groove 25, and laterally extending supportplates 26 and 2'! that are integrally formed on the body element l9, andthe bottom faces of the laterally extending support plates are flushwith the bottom of the groove 25 in the body element 19. At the frontside of the groove 25 there is a cut 28 extending upwardly into the bodyelement l9 and forming a lip-like element 29 that forms the front faceof the groove A cap screw 30 is slidably passed through the lip 29 andthreaded into the body element l9.

A fiat file element 3| fits closely in the groove 25 and rests againstthe file support extensions 26 and 21. The file 3| may be rigidly heldin the groove 25 by screwing the screw 30 into the body element l9whereupon the head of the screw 30 will engage and press the lip 29against the edge of the file 3| to rigidly bind and hold the file 3| inthe groove 25 as shown. Before tightening the file in the groove 25 thefile may be tilted slightly to any desired angle to suit the user of thetool as shown and for purposes that Will later be described.

The rear end portion of the body element i9 is provided with a pair Ofthreaded holes 32 and 33 therethrough for purposes that will later bedescribed.

In the hole 33 is threaded a thumb screw 3-5 on which is threaded awinged lock nut 35 to lock the adjusting screw 34 in adjusted positionsfor purposes that will later be described.

The toolas thus far described may be used on hand saws, and may be madeready for use, and may be used as follows.

The saw may be filed and set by pressing and bending each successivetooth in opposite directions in the usual manner. In so setting a sawthe teeth may not bend uniformly and the points of some of the teeth mayproject sideways more than others, therefore the saw will not cut evenlyand smooth and will be harder to push, therefore it is desirable to evenup or align all the points of the teeth of the saw, and this may be doneby using my improved tool as follows:

The file 3| may be set in a tilted position in the groove 25 tosubstantially match the angle of the set saw teeth. This having beendone, the tool may be laid on the side of the saw with the file restingon or being positioned over the saw teeth. This having been done theadjust-- ing screw 3 may be screwed up or down so the lower end of thescrew 36 will engage the saw blade and raise or lower the rear end ofthe body element l9 to rock the tool until the file 3i engages the sawteeth to the desired'degree whereupon the winged lock nut may betightened on the thumb screw 34 to lock the thumb screw 34 in itsadjusted position. Now the tool may be moved back and forth the lengthof the saw blade whereupon the file will cut the saw tooth points to apoint where the gauge insert element 24 will engage and slide on theside of the saw blade; the same process is repeated on the other side ofthe saw, whereupon the points of the saw teeth are all cut to alignmentand the saw is now ready for use.

The tool may be similarly prepared for use on circular saws, although abetter job may be obtained if the tool were" moved in a uniform circularline of travel. To accomplish this movement, the tool is provided with acenter holding extension arm 36 that has a narrowed end portion A thatis designed to fit snugly between the ear-like elements 22 and 23 of thebody element 58, and the extension arm 36 lies on top of the rearportion of the body element H. The arm 36 is provided with a pair ofholes 31 and 38 that will register with the holes 32 and 33 in the bodyelement H3. The hole 38 is larger than the hole 33 for reasons that willlater be made obvious. The arm 33 is also provided with a longitudinallypositioned slot 39.

Slidably positioned in the slot 39 is a pin id that is integrally formedon the end of a; larger roller pin ll thereby forming a shoulder 32which slidably rests against the under side of the arm 36; the outer endof the roller pin 4'! is. provided with a head 43 that is integrallyformed thereon. Revolvably mounted on the roller pin GI is a roller 45having an outwardly extending flange portion 45 integrally formedthereon that is revolvably positioned against the under side of the arm36, and the roller i l-65 is retained on the roller pin ll by the pinhead 43. The outer end of the pin to is threaded to receive a threadedwing nut 45.

A slide block 47 having a tongue 38 integrally formed thereon ispositioned on the upper side of the arm 36 with the tongue 28 snugly andslidably fitted in the slot 39 of the arm 36. The pin fiil slidablypasses through a hole 49 in the slide block ll d8 so that the wing 46may be screwed on the pin 49 to pull the pin shoulder d2 against thebottom side of the arm 36 and press the slide plate i-l against theupper side of the'arm 35 to rigidly bind and hold the roller pin ll inadjusted positions along the arm 35.

The arm 35 is attached to the body element 29 by placing the armextension A between the ear-like elements 22 and Z3 and then passing athumb screw 50 through the loosely fitting hole 3? in the extension arms36 and then screwing the screw into the threaded hole 32 in the bodyelement to, and the Wing nut 35 will be loosely housed in the hole 38 inthe extension arm 35.

Now to apply the tool to a circular saw 5!, the wing nut is loosened onthe pin 15, and the roller i t placed in the arbor hole in the center ofthe saw with the G5 resting against the side of the saw. Now the tool isand arm 36 may be moved longitudinally until the points 5hr of the sawteeth will be engaged by the central longitudinal portion of the file3!. This adjustment having been made, the Wing nut 43 is tightened onthe pin whereby the roller pin it is rigidly locked on the extension arm3'8 at the proper place to maintain the file 31 in its radial adjustedposition. This adjustment having been made, the angular adjustment ofthe position of the file 3i relative to the angle of the set of the sawteeth may be made precisely the same as previously described in the forepart of this specification, and the tool is ready for use. Now by movingthe tool in the circular motion as will be governed by the extension arm35 and pin it and roller 46, the file 3! Will engage and cut the points51a of the saw teeth until the curved gauge element 24 engages the sideof the saw, and the end of the screw 84 already engaging the side of thesaw, the file 31 will no longer cut the teeth points Slaas the file 3iis moved thereover, therefore all the points am of the saw teeth are inperfect alignment. Now the saw may be turned over and the tool similarlyapplied to the row and the oppositely set teeth may also be accuratelyaligned whereupon the saw is then ready for use.

Now to connect the tool for use on hand saws: A cross bar 52 having atransversely positioned tongue 53 integrally formed thereon issubstituted for the aforementioned roller pinidll, and the tongue 53 issnugly and slidably positioned in the slot 39 in the extension arm 35,and a bolt iila is slidably passed through holes in the slide block H-lfi and the cross bar El -53, and through the slot in the extension bar36. The wing nut 48 is threaded on the bolt 42a and engages the slideblock 47 to pull the slide block 31 and cross bar 52 toward eachsotherto rigidly clamp and hold the cross bar 52" at adjusted positions alongthe extension arm 36, and

the tongue 58 serves to maintain the cross bar 52 at an angle of ninetydegrees to the extension arm 36 at all times. Grooved rollers 54 and 55are revolvably carried on the under side of the cross-bar 52 and onheaded pins 56 and 51 that are carried one on either end of thecross-bar 52 and pass therethrough, and nuts 58 and 59 are threaded onthe upper ends of the pins 56 and 51 and bear against the upper side ofthe cross bar 52 to rigidly bind and hold the pins 56 and, 51 in placein the ends of the cross bar 52. This conversion of the tool is used byplacing the smooth back edge of the band saw 66 in the grooves of therollers 55 and 55, and loosening the wing nut 46 on the bolt 46awhereupon the extension arm 36 and tool body 19 may be movedlongitudinally until central longitudinal portion of the file 3i restsagainst the tooth points 62a of the band saw 68, and the rollers 54 and55 serve to maintain the file 3! in its proper longitudinal positionrelative to the saw tooth points 66a. Now the tool may be moved alongthe length of the saw whereupon the file 3| will cut the saw toothpoints 6611 to alignment whereupon the wing nut 46 may be tightened forlocking purpose. This having been done, the tool may be turned over andsimilarly applied to the other side of the saw to similarly cut the sawtooth points 60?) to alignment the same as the tooth points 60a.

In the tool as shown in Figures 13, 14, 15, 16, 17, and 18, the end A ofthe extension arm 36 fits snugly between the ear-like elements 22 and23, therefore the body element 19 will remain in alignment with theextension arm 36 but the thumb screw 56 being loose in the hole 31 willpermit the body element ii] to rock so that the lower end of the screw34 will always rest on the saw body 51 or 66 and as the file 3! cuts thesaw tooth points the curved gauge element 24 will also engage the sawbody 5| or 68 and a uniform job of cutting and aligning the saw toothpoints Will be done on both sides of the saw.

While the foregoing specification and description have had reference tothe spring type tooth of saws, it is to be noted that swage tooth sawteeth bear the same characteristics so far as the tooth pointsprojecting on opposite sides of the saW blade is concerned, thereforethe foregoing described tool will work equally as well on the swagetooth type saw as it will on the spring tooth type of saw.

Such modifications of my invention may be employed as lie within thescope of the appended claims without departing from the spirit andintention of the invention. Now having fully shown and described myinvention, what I claim is:
